Abstract

The method involves reducing an adhesion force between two sheets following one another in an overlapping stream by lifting a trailing edge of one sheet. The sheet trailing edge is lifted by blowing under from a rear position. The sheet is aligned in a sheet transport direction before the trailing edge of the sheet is lifted. The sheet is aligned laterally at the same time as the trailing edge of the sheet is lifted. Independent claims are also included for the following: (A) an apparatus for guiding sheets to a sheet processing machine (B) a printing press comprising a sheet stack feeder.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Führen von Bogen zu einer Bogen verarbeitenden Maschine, insbesondere Druckmaschine.The invention relates to a method and a device for guiding from sheet to sheet-processing machine, in particular printing machine.

Insbesondere bei der Verarbeitung von Bogen mit glatter Oberfläche, wie z. B. gestrichenem Papier, beschichteten Bogen oder Folien, besteht das Problem, dass die Bogen im Schuppenstrom durch Adhäsionskräfte aneinander haften. Dies führt dazu, dass beim Abziehen des ersten ausgerichteten Bogens der jeweils zweite Bogen mitgenommen wird und beim Zusammenschieben der Schuppe während des Ausrichtens des ersten Bogens der zweite Bogen mit verschoben wird, welches zu einem Fehlbogentransport und zum Stillstand der Bogen verarbeitenden Maschine führt.Especially when it comes to processing of sheets with a smooth surface, such as B. coated paper, coated sheets or foils, there is the problem that the arches in the shingled stream due to adhesive forces be liable. This leads to, that when pulling out the first aligned sheet of each second sheet is taken and when pushing the scale together during the Aligning the first sheet with the second sheet being moved which leads to a misfeed transport and to a standstill of the sheets processing machine leads.

Bei der DE 44 13 089 C2 ist es vorgesehen, den Bogenstrom kontinuierlich von unten mit Blasluft zu unterblasen, um so die Adhäsionskräfte zwischen zwei aufeinanderfolgenden Bogen zu vermindern. Die Blasluft unter dem Bogenstrom beunruhigt jedoch das gleichmäßige Führen der Bogen.In the DE 44 13 089 C2 it is provided that the stream of sheets is continuously blown from below with blown air so as to reduce the adhesive forces between two successive sheets. However, the blowing air under the arc stream worries the even guiding of the arcs.

Die Aufgabe der Erfindung besteht nunmehr darin, ein alternatives Verfahren und eine Vorrichtung zu schaffen, mit welcher die Adhäsionskräfte zwischen dem Bogen eines Bogenstroms wirksam vermindert werden kann.The object of the invention is now in an alternative method and apparatus create with which the adhesive forces between the arc of an arc current can be effectively reduced.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1, 4 und 12 gelöst.The object is achieved by the Features of the claims 1, 4 and 12 solved.

Es ist ein besonderer Vorteil der Erfindung, dass die Aushebung von Adhäsionskräften zwischen aufeinanderliegenden bzw. aufeinanderfolgenden Bogen durch eine Trennungsmaßnahme eingeleitet wird, die von oben auf den Schuppenstrom wirkt. Durch diese Maßnahme kann die Trennung sehr gezielt in einem bestimmten Bereich des Schuppenstroms erfolgen, in welchem der übrige Schuppenstrom unbeeinflusst bleibt.It is a particular advantage of the Invention that the lifting of adhesive forces between superimposed or successive arc is initiated by a separation measure, which acts on the stream of shingles from above. This measure can the separation very specifically in a certain area of the scale flow in which the rest Scale flow remains unaffected.

Durch die Ausbildung der Anhebevorrichtung als Blas-Sog-Düse kann die Bogenhinterkante auch bereits angehoben werden, wenn diese noch in Bewegung ist und nicht erst, wenn ein Anschlagen an den Vordermarken erfolgt ist. Eine Seitenausrichtung des Bogens kann weiterhin ohne Behinderung erfolgen.By designing the lifting device as Blow-suction nozzle the trailing edge of the sheet can already be raised if this is still in motion and not only when it strikes the Front brands is done. A side orientation of the sheet can continue to be done without disability.

Bei einer vorteilhaften Weiterbildung bläst eine zusätzliche Freistrahldüse Blasluft zwischen die angehobene Bogenhinterkante des ersten Bogens und die Oberseite des nachfolgenden Bogens.With an advantageous further education blows one additional Open Jet Blow air between the raised trailing edge of the first sheet and the top of the next sheet.

Ein Absatz an der Unterseite der Bogenanhebevorrichtung ist in einem kleinen Abstand hinter der Blas-Sog-Düse angeordnet und unterstützt die Trennung der Bogen, falls der zweite Bogen durch Adhäsionskräfte mit angehoben wird.A paragraph at the bottom of the Sheet lifting device is arranged at a small distance behind the blow-suction nozzle and supports the separation of the arches if the second arch is joined by adhesive forces is raised.

Eine in Transportrichtung angeordnete Linearführung ermöglicht die Einstellung der erfindungsgemäßen Vorrichtung auf das zu verarbeitende Bogenformat.One arranged in the direction of transport linear guide allows the setting of the device according to the invention processing sheet format.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden beschrieben.An embodiment of the invention is shown in the drawings and is described below.

Eine Bogen 7 verarbeitende Maschine, z. B. eine Druckmaschine 1, weist einen Anleger 2, mindestens ein Druckwerk 3 bzw. 4 und eine Ausleger 6 auf. Die Bogen 7 werden von einem Bogenstapel 8 entnommen und vereinzelt oder schuppenförmig über einen Zuführtisch 9 den Druckwerken 3 und 4 zugeführt. Diese enthalten in bekannter Weise jeweils einen Plattenzylinder 11; 12. Die Plattenzylinder 11 und 12 weisen jeweils eine Vorrichtung 13, 14 zum Befestigen flexibler Druckplatten auf. Darüber hinaus ist jedem Plattenzylinder 11; 12 eine Vorrichtung 16; 17 für den halb- oder vollautomatischen Druckplattenwechsel zugeordnet.An arch 7 processing machine, e.g. B. a printing press 1 , instructs an investor 2 , at least one printing unit 3 respectively. 4 and an outrigger 6 on. The bow 7 are from a sheet stack 8th removed and isolated or in scaly form on a feed table 9 the printing units 3 and 4 fed. These each contain a plate cylinder in a known manner 11 ; 12 , The plate cylinder 11 and 12 each have a device 13 . 14 for attaching flexible printing plates. In addition, each plate cylinder 11 ; 12 a device 16 ; 17 assigned for the semi or fully automatic printing plate change.

Der Bogenstapel 8 liegt auf einer gesteuert anhebbaren Stapelplatte 10 auf. Die Entnahme der Bogen 7 erfolgt von der Oberseite des Bogenstapels 8 mittels eines sogenannten Saugkopfes 18, der unter anderem eine Anzahl von Hub- und Schleppsaugern 19, 21 für die Vereinzelung der Bogen 7 aufweist. Darüber hinaus sind Blaseinrichtungen 22 zur Auflockerung der oberen Bogenlagen und Tastelemente 23 zur Stapelnachführung vorgesehen. Zur Ausrichtung des Bogenstapels 8, insbesondere der oberen Bogen 7 des Bogenstapels 8, sind eine Anzahl von seitlichen und hinteren Anschlägen vorgesehen.The stack of sheets 8th lies on a stack plate that can be raised in a controlled manner 10 on. The removal of the bow 7 done from the top of the sheet stack 8th by means of a so-called suction head 18 , which among other things a number of lifting and dragging vacuums 19 . 21 for separating the sheets 7 having. In addition there are blowing devices 22 for loosening the upper sheet layers and touch elements 23 intended for stack tracking. To align the stack of sheets 8th , especially the upper bow 7 of the sheet stack 8th , a number of side and rear stops are provided.

Der Zuführtisch 9 weist mindestens ein Transportband 26, vorzugweise ein Saugband, zum Transport der Bogen bzw. des Bogenstroms an vordere Ausrichtmarken – sogenannte Vordermarken 27 – auf. Eine Seitenausrichtvorrichtung 28 ist ebenfalls im vorderen Bereich des Zuführtisches 9 angeordnet. Der ausgerichtete Bogen 7 wird von einem Vorgreifer 29 ergriffen und einer Zuführtrommel 31 zugeführt.The feed table 9 has at least one conveyor belt 26 , preferably a suction belt, for transporting the sheets or the sheet flow to front alignment marks - so-called front marks 27 - on. A side aligner 28 is also in the front area of the feed table 9 arranged. The aligned bow 7 is by a pre-gripper 29 seized and a feed drum 31 fed.

Oberhalb des schuppenförmigen Bogenstroms ist in etwa im Abstand der zu verarbeitenden Formatlänge 1 von den Vordermarken 27 eine Bogenanhebevorrichtung 32 angeordnet. Diese weist im Wesentlichen mindestens eine Blas-Sog-Düse 33, vorzugsweise eine Anzahl von nebeneinander über die Formatbreite des Bogenstroms verteilt angeordnete Blas-Sog-Düsen 33, auf. Die Blas-Sog-Düse 33 ist so ausgerichtet, dass ein in Bogentransportrichtung gerichteter Blasluftstrahl im Wesentlichen tangential in geringem Abstand a (z. B. a = ca. 4 Millimeter) über den Bogenstrom ausgeblasen wird. Durch Ausnutzung des sogenannten "aerodynamischen Paradoxon"-Effektes wird die Bogenhinterkante angehoben und somit vom darunterliegenden nachfolgenden Bogen getrennt.Above the scale-like arc stream is approximately at a distance from the format length to be processed 1 from the front brands 27 a sheet lifting device 32 arranged. This points essentially at least one blow-suction nozzle 33 , preferably a number of blow-suction nozzles arranged next to one another over the format width of the sheet stream 33 , on. The blow-suction nozzle 33 is aligned in such a way that a blowing air jet directed in the sheet transport direction is blown out essentially tangentially at a small distance a (e.g. a = approx. 4 millimeters) above the sheet stream. By utilizing the so-called "aerodynamic paradox" effect, the trailing edge of the sheet is raised and thus separated from the subsequent sheet below.

Zur Unterstützung dieses Trenneffektes ist mindestens eine, vorzugsweise eine Anzahl von nebeneinander angeordneten Freistrahldüsen 34 vorgesehen, deren Blasluftstrahl schräg von oben auf die Bogenhinterkante gerichtet ist, so dass der Blasluftstrahl zwischen die Unterseite des ersten Bogens und die Oberseite des nachfolgenden, unteren Bogens eintreten kann. Sämtliche Freistrahldüsen 34 sind quer zur Bogentransportrichtung verstellbar angeordnet und an gewünschter Position arretierbar. Ein kleiner Absatz 36 an der Unterseite der Anhebevorrichtung 32 liegt in Bogentransportrichtung gesehen in einem kleinen Abstand b (z. B. b = ca. 2 Millimeter) vor der Blas-Sog-Düse 33. Diese Maßnahme begünstigt das Trennen zweier aufeinanderfolgender Bogen, wenn der zweite Bogen z. B. durch den Statik, Ahäsionskraft mit angehoben werden sollte.To support this separation effect is at least one, preferably a number of free jet nozzles arranged next to one another 34 provided, the blown air jet is directed obliquely from above onto the trailing edge of the sheet, so that the blown air jet can enter between the underside of the first sheet and the upper side of the subsequent, lower sheet. All free jet nozzles 34 are adjustable across the sheet transport direction and lockable at the desired position. A small paragraph 36 on the underside of the lifting device 32 is in the sheet transport direction at a small distance b (e.g. b = approx. 2 millimeters) in front of the blow-suction nozzle 33 , This measure favors the separation of two consecutive sheets when the second sheet z. B. should be increased by the static, adhesive force.

Um die Anhebevorrichtung 32 auf die zu verarbeitende Bogenformatlänge 1 einstellen zu können, ist auf einer Seite des Zuführtisches 9 eine Linearführung 37 vorgesehen, an welcher die Anhebevorrichtung 32 verschiebbar gelagert ist.To the lifting device 32 to the sheet format length to be processed 1 To be able to adjust is on one side of the feed table 9 a linear guide 37 provided on which the lifting device 32 is slidably mounted.

Ein Luftversorgungskanal 38 im Inneren der Anhebevorrichtung 32 versorgt die Blas-Sog-Düse 33 und die Freistrahldüse 34 mit Blasluft von einer nicht dargestellten Blasluftquelle. Die Blasluft strömt kontinuierlich aus. Bei einer Weiterentwicklung ist es vorgesehen, die Blasluft im Takt der Bogen verarbeitenden Maschine zu takten. Zu diesem Zweck wird ein Rotationsventil bzw. werden elektromagnetisch ansteuerbare Ventile eingesetzt.An air supply duct 38 inside the lifting device 32 supplies the blowing and suction nozzle 33 and the free jet nozzle 34 with blown air from a blown air source, not shown. The blown air flows out continuously. In a further development, it is planned to cycle the blown air in time with the sheet processing machine. A rotary valve or electromagnetically controllable valves are used for this purpose.

Es wird alternativ vorgeschlagen, die Düse 33 als Sauggreifer auszubilden und anstatt mit Blasluft mit Saugluft zu beaufschlagen, während die Freistrahldüse 34 weiterhin mit Blasluft versorgt wird.It is alternatively suggested the nozzle 33 trained as a suction cup and instead of blowing air with suction air while the free jet nozzle 34 continues to be supplied with blown air.

Die Bogen 7 werden vom Bogenstapel 8 mittels des Saugkopfes 18 vereinzelt und schuppenförmig mittels Transportband 26 den Vordermarken 27 zugeführt. Durch die im Bogenlängenabstand 1 vor den Vordermarken 27 oberhalb des Bogenstroms angeordnete Bogenanhebevorrichtung 32 wird die Bogenhinterkante des jeweils ersten Bogens 7 des Bogenstroms angehoben und vom Freiluftstrahl der Freistrahldüse 34 unterblasen.The bow 7 are from the sheet pile 8th by means of the suction head 18 isolated and scale-like by means of a conveyor belt 26 the front brands 27 fed. By the in the arc length spacing 1 in front of the front brands 27 Sheet lifting device arranged above the sheet flow 32 becomes the trailing edge of the first sheet 7 of the arc flow and from the free jet of the free jet nozzle 34 under blow.

Das Anheben der Bogenhinterkante erfolgt vorzugsweise, sobald die Bogenvorderkante die Vordermarken erreicht hat. Durch diese Maßnahme kann der erste Bogen daraufhin oder gleichzeitig seitlich ausgerichtet werden, ohne den zweiten Bogen mitzunehmen.Raising the trailing edge of the sheet is preferably done as soon as the leading edge of the sheet the front marks has reached. This measure can the first sheet then or laterally aligned without taking the second sheet.
